Detection of Secretory Immunoglobulin A in Human Colostrum as Mucosal Immune Response Against Proteins of the Type III Secretion System of Salmonella, Shigella and Enteropathogenic Escherichia Coli

Abstract

The extraordinarily high frequency of antibodies in colostrum of puerperal women detected in this study against these multiple enteric pathogens shows evidence of immunological memory and prior exposure to these pathogens, in addition to its possible protective role against infection.
